What is nutropic?
Definition of nutropic
nutropicmeans drugs to enhance cognitive function andsupplementThis is a generic term for Specifically,memory, ,attentiveness, ,(powers of) concentrationIt improves cognitive functions and protects the nervous system, such as
- Cognitive Function Improvement: Ability to learn, memory,attentivenessand others are improved.

Much research has been conducted in this area, and effectiveness tends to be evaluated based on scientific evidence.
History and evolution of nutropics
The concept of nutropics was first introduced in the 1970s by Romanian psychologist and chemist Cornelu E. Gürgea.
The first use of the term was in his book Pharmacology and Clinical Use of Piracetam.
In the beginningPiracetamHowever, nowadays, the use of drugs is limited to a wide variety of drugs andsupplementis considered a nutropic.
History of Nutropic
- 1970s: Research begins with Piracetam.
